Check and have HijackThis fix the following lines:

F2 - REG:system.ini: Shell=Explorer.exe "C:\WINDOWS\eksplorasi.exe"

O4 - HKLM\..\Run: [Bron-Spizaetus] "C:\WINDOWS\ShellNew\sempalong.exe"
O4 - HKCU\..\Run: [Tok-Cirrhatus] "C:\Documents and Settings\Administrator\Local Settings\Application Data\smss.exe"

Now restart your computer.

Next, go HERE to run Panda's ActiveScan
  • Once you are on the Panda site click the Scan your PC button
  • A new window will open...click the Check Now button
  • Enter your Country
  • Enter your State/Province
  • Enter your e-mail address and click send
  • Select either Home User or Company
  • Click the big Scan Now button
  • If it wants to install an ActiveX component allow it
  • It will start downloading the files it requires for the scan (Note: It may take a couple of minutes)
  • When download is complete, click on My Computer to start the scan
  • When the scan completes, if anything malicious is detected, click the See Report button, then Save Report and save it to a convenient location. Post the contents of the ActiveScan report
Also run HijackThis again and post a fresh log.

Thanks for help. I followed instructions until Scan Now in Panda's Active Scan. However, I aborted downloading from there when I got malware warning from my anti-virus software:

Malware name: Win32:CTX
Malware type: Virus/Worm
VPS version: 0637-0, 11.09.2006

what now? pls help!

It's a False Positive. Pandasoftware is a MOST reputable site. Please DISABLE your antivirus temporarily, and run the scan.
